4-5 hours to pull down the diff and press in the bushings? You guys are slow

Hehe took my shop a few hours to get only the rear, big diff bushing out. Quite a PITA. They even had to flex their bushing removal tools a bit to get them into the tight space. It's probably better to remove the whole subframe when replacing all the bushings.

Seems like an unnecessary waste of time to me. Granted, I have a touch of "MacGyver" in me and I'm more resourceful than some, but i made my own press tooling with tube scraps slightly larger than the stock bushings,a pair of sized "caps" slightly smaller than the oem bushings and all-thread, works great. I would imagine BMW's special tools for the app or equivalent would be even better...but unnecessarily expensive because they include special tooling to draw the junk oem mounts back in...basically any large decent brand universal bushing puller kit will have the right sized caps and sleeves. really not terrible to do with subframe in the car.

IIRC the metal "tube" or "ring" to press out the bushing was hitting somewhere on the subframe, so they couldn't press the bushing out totally. They then flexed some indents in that tube. Definitely doable without removing the subframe but needs good DIY skills.

So what you're saying is, I should install this with my M3 suspension bits at the same time? I have M3 subframe bushings sitting in my garage.

You certainly could, I't would be silly not to swap em if you already have the bushings, big time saver considering your halfway there...obviously they didn't seem to be a necessity in any of the cars I've tested, so it's your discretion. Obviously there's extra time/cost in pulling the entire subframe, but your already pretty deep at that point...totally your decision.

ok so my partial kit arrived took me an hour to install. this kit is well made I must say, very high quality bushings and parts. BUt ghetto instructions lol just kidding. i did a burnout and didnt get any wheel hop. I'm waiting for it to rain to do some more testing because thats when the WH monster rears its ugly head. Also keep in mind I have the turner delrin bushings.
